Log Message:
-----------
As Dmitry added scanf() support for the 'hh' conversion modifier
almost 5 years ago, also add support for scanf() conversion macros for
8-bit data types to <inttypes.h>: SCNd8, SCNdLEAST8, SCNdFAST8, SCNi8,
SCNiLEAST8, SCNiFAST8, SCNo8, SCNoLEAST8, SCNoFAST8, SCNu8,
SCNuLEAST8, SCNuFAST8, SCNx8, SCNxLEAST8, SCNxFAST8
